High-temperature high-pressure coaxial Rotational Viscometer

The high-temperature high-pressure coaxial rotational viscometer measures the shear resistance of a sample by rotating the inner and outer cylinders relative to each other within a sealed chamber, converting this resistance into viscosity values. It is used for detecting the rheological properties of materials such as petroleum drilling mud and polymer melts under simulated downhole high-temperature and high-pressure conditions.
Selection
When selecting, ensure the instrument's maximum temperature and pressure tolerance covers experimental requirements, consider material compatibility with sample corrosiveness, verify the speed range meets shear rate demands, check data acquisition accuracy, and evaluate the ease of sample loading and cleaning.
